Abstract (en)

[origin: US2018171051A1] An aqueous copolymer dispersion is formed by emulsion polymerization of a monomer mixture comprising (a) 20 to 80 wt. % of one or more (meth)acrylic acid esters A, whose homopolymer(s) have a Tg>25° C. and at least one has a biorenewable carbon content of at least 50 wt. % of the total carbon content of the ester; (b) 19 to 79 wt. % of one or more (meth)acrylic acid esters B whose homopolymer(s) have a Tg<25° C.; (c) 0.5 to 10 wt. % of at least one monomer selected from unsaturated sulfonic, phosphoric and phosphonic acids, and unsaturated carboxylic acids, anhydrides and amides thereof; (d) up to 10% by weight of one or more functional monomers selected from hydrolysable silane compounds, epoxy-containing compounds, ureido-containing compounds and carbonyl-containing compounds, and (e) less than 5 wt. % of one or more further monomers, wherein the total percentages of comonomers (a) to (e) equals 100%.
